Basin Engineering was formed in 1995 to provide high quality, experienced drilling, completion and production engineering and well-site services. We pride ourselves in retaining only the best talent, and know that our personnel set Basin apart from other firms. Each of our principals come from the ranks of oil and gas operating companies where they received extensive operations experience and managed the associated financial responsibilities. We understand the needs of our clients.

Operations History

Our operator-based background enables us to assist Basin clients with knowledge and understanding that only comes from "sitting on the operator's side of the desk". To date, Basin Engineering has worked for dozens of clients from multinational oil companies to small independent producers who operate only a handful of wells. We have managed large drilling budgets on technically challenging, deep, high-pressured, and horizontal wells as well as shallow, vertical wells that may only take a few days to drill and complete. Basin engineers have provided expert witness testimony before state and federal regulatory agencies and civil judges and juries. As a respected contract operator, we have effectively and fiscally managed oil and gas interests from geologic inception through a well's productive life to abandonment. Basin Engineering has an outstanding record of service and ethical responsibility to all of our clients.
